Specs: Efficiency, Weight, and Ports
Conversion efficiency
The STAR panel leads with a 25% conversion efficiency rating, slightly higher than the ZOUPW’s 23.5%. This difference matters when sunlight is limited or the angle is not perfect. Both panels use monocrystalline cells, which generally outperform polycrystalline alternatives in low-light conditions. The STAR’s higher percentage suggests it can capture more energy from the same amount of sun. For you, this means potentially faster charging times for your power station during peak hours. The ZOUPW remains competitive, but the STAR holds a small technical advantage in pure energy capture per square inch.
Portability and weight
Portability is a clear win for the ZOUPW. It weighs just 9.48 pounds, making it easy to carry on camping trips or hike to a remote spot. The STAR is significantly heavier at 16.5 pounds. The ZOUPW also folds down to a compact size with a magnetic handle, designed for frequent transport. The STAR features a frameless design intended for RV installation, not for carrying around. If you need to move the panel between locations, the ZOUPW’s lightweight build and foldable structure are far more practical for your mobile energy needs.
Direct device charging
The ZOUPW includes built-in intelligent controller ports, allowing you to charge devices directly without a power station. It offers one USB-C port (PD 15V/3A) and two USB-A ports, including QC3.0 support. The STAR data does not list any direct charging ports or built-in controllers. This means you must route power through a battery or generator with the STAR. For quick phone or camera charging while outdoors, the ZOUPW provides immediate convenience. The STAR requires additional equipment to achieve similar direct charging capabilities.
Waterproofing and durability
The ZOUPW carries an IP67 rating, meaning it is fully waterproof against rain and splashes. It also uses ETFE coating, which offers better heat resistance and light transmittance than standard PET materials. The STAR features a frameless design that helps prevent dust and water buildup, promoting rain self-cleaning. However, the specific IP rating for the STAR is not listed in the data. The ZOUPW’s certified IP67 rating provides a measurable standard for weather resistance. For unpredictable outdoor conditions, the ZOUPW’s documented waterproofing offers clearer protection for your investment.
Connectivity and compatibility
The ZOUPW comes with a 5-in-1 universal connector cable, including DC8020, XT60, Anderson, DC7909, and DC5521 ports. This covers 99% of popular power stations like Jackery, EcoFlow, and Bluetti without extra adapters. The STAR data does not specify included connectors or cable types. While the STAR is designed for RV use, you may need to purchase separate wiring or adapters for portable power stations. The ZOUPW’s comprehensive cable kit makes it easier to connect to various devices right out of the box.
Which solar panel suits your needs
Portable power station users needing direct charging
The ZOUPW includes built-in USB-C and USB-A ports, allowing you to charge devices directly without a power station. Its IP67 waterproof rating and foldable design make it ideal for camping or emergency use. The 5-in-1 cable ensures compatibility with most portable generators, offering versatility you cannot get from a fixed panel.
RV owners seeking permanent roof installation
The STAR panel features a frameless design that prevents dust and water buildup, reducing maintenance needs. Its 25% conversion efficiency is slightly higher than the ZOUPW’s. With pre-drilled holes for easy mounting, this rigid unit is better suited for fixed RV installations where portability is not a priority.
Users prioritizing maximum energy conversion
If every watt counts, the STAR panel’s 25% conversion efficiency offers a slight advantage over the ZOUPW’s 23.5%. This higher efficiency helps capture more power in low-light conditions or when the panel angle is not optimal. The frameless design further boosts output by eliminating shading from frames.
